Analysis

Analysis is the process of breaking a complex topic or substance into smaller parts to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle (384–322 B.C.), though analysis as a formal concept is a relatively recent development.[1]

Philosophical analysis is a method of inquiry in which one seeks to assess complex systems of thought by ‘analysing’ them into simpler elements whose relationships are thereby brought into focus. Routledge Encyclopedia of Philosophy. 1998, entry under ‘Conceptual Analysis’ by Robert Hanna
